Chevy HHR suddenly not starting, cranks fine, runs great.
Last night I would get in the car (2007 HHR 2.2 LT) and the car would crank like normal but never fire.
I messed with the gas peddle a bit while trying to start it and got it to start a couple of times. Also I tried to hook jumpers up to my truck even though the battery seems fine and it did not seem to make a difference.
Once running it ran great. I noticed that the check engine light did come on after I got it started that first time. When I would turn the engine off if I tried to restart imediately there was not a problem but if I wait a few minutes it was like starting the whole process over again.
Its a mystery to me as to why it can be so hard to start and require me to try 5 or 10 times but then run great once it actually starts.
Some other info is that it has not had a problem before, the gas was down to about 40 miles left when my wife filled it up, and the gas cap had not been put back on correctly.
From scouring the internet I see that if the gas cap is not securely tightened with alreast 3 clicks it can cause the engine light to come on.
I checked the fuses as well to make sure they were all plugged in well.
Also it seems like it might be the fuel pump in that it might not be priming the engine correctly. (that is my uneducated guess)
I do normally hear a little hum when I try to start the car and believe I was hearing it last night as well.
If the fuel pump was out would the car start at all and if so run so well? I added fuel cleaner to the gas last night and drove about 30 miles without any problems.
Just wont start. I appreciate any ideas??
